GeoIP2 Web Services

What is GeoIP2 and how does it differ from GeoIP Legacy?

MaxMind's GeoIP2 web services and GeoIP2 databases are an evolution of our original GeoIP web services and databases, which we now refer to as GeoIP Legacy. See What's New in GeoIP2 for details on enhancements in GeoIP2.

What is GeoIP2 Precision data?

GeoIP2 Precision data is our most accurate data. Our GeoIP2 Precision City and Omni web services accurately geolocate 3% more IPs to cities and 5% more IPs to postal codes than the GeoIP2 and GeoIP Legacy downloadable databases.

为什么我查询次数的使用速度比我的预计要快?

Search engine spiders may be crawling your site and depleting your GeoIP2 web service queries. The robots exclusion standard may help prevent search engines spiders from doing so.

您可以写代码为客户检查用户-代理页头,从而识别是否是搜索引擎蜘蛛造成的问题。

如果您使用了机器人排除标准,但仍发现查询次数的使用速度快于预计速度, 我们建议您把每次网络服务查询都记录下来, 以便更好地了解是什么导致您的代码 启动网络服务查询。

如果我的查询次数即将用尽,我会收到警告吗?

We will send a warning email when your remaining queries for a GeoIP2 web service falls below 10,000.

Should I choose the GeoIP2 web service or GeoIP2 database?

It depends on your needs. There are four main considerations.

Our GeoIP2 Precision City and Omni web services accurately geolocate 3% more IPs to cities and 5% more IPs to postal codes than the GeoIP2 and GeoIP Legacy downloadable databases.

Our web service has had 99.99% uptime since January 2010 and responds quickly, but with a local copy of the database you are not dependent on the availability of our servers or a specific network route. Also, you can perform many more queries per second with a local database.

You need to download GeoIP2 databases yourself in order to have access to the latest and most accurate GeoIP2 data. With the GeoIP2 Web Services, you always receive the latest data available.

Once you have purchased a license to a downloadable database, there is no limit on the number of queries you can perform on that database. Based on the number of queries you are doing per month, you may find that either the downloadable databases or the web services are less expensive.

GeoIP2 and GeoIP Legacy Databases

How accurate are your GeoIP2 and GeoIP Legacy databases?

MaxMind tests the accuracy of the GeoIP2 and GeoIP Legacy Databases on a periodic basis. In our recent tests, the databases were 99.8% accurate on a country level, 90% accurate on a state level in the US, and 83% accurate for cities in the US within a 40 kilometer radius. For more details, see GeoIP2 City Coverage and Accuracy.

MaxMind支持IPv6地址吗?

Yes! Our GeoIP2 databases and web services return data on IPv6 addresses. For more details, please see our IPv6 Information and FAQ page.

贵公司的数据库中存有多少IP地址? 包括多少国家?

请参阅我们有关 IP配置细节的页面。

What is the difference between the GeoIP Legacy ISP and Organization databases?

ISP数据库一般含有ISP名称。 但是,如果 我们无法获取ISP,我们则会将 该IP地址块所属的机构名称包括在内。 例如,ISP数据库经常含有高校名称,而不是高校的ISP。

在只能提供ISP或机构名称的情况下, GeoIP ISP和机构数据库所生成的数据相同。 这种情况下的 共享数据通常代表ISP。 在ISP与机构名称均可提供的情况下, GeoIP ISP和机构数据库分别生成ISP数据和机构数据。

How many lookups can your GeoIP2 or GeoIP Legacy APIs support per second?

Please see our GeoIP Legacy benchmarks. GeoIP2 benchmarks will be added in the future.

Which cities are in the GeoIP2 and GeoIP Legacy City databases?

We offer a CSV file that contains all the cities in the GeoIP Legacy City database. The equivalent for GeoIP2 is forthcoming in later 2014.

GeoIP2 and GeoIP Legacy Database Updates

How often are the GeoIP2 and GeoIP Legacy databases updated?

The GeoIP2 and GeoIP Legacy Country and City and GeoIP Legacy Region databases are updated every Tuesday. All other databases are updated on the first Tuesday of the month.

How often should I purchase GeoIP2 or GeoIP Legacy database updates?

鉴于数据经常变化,我们建议您每1到3个月即应更新您的产品。

GeoIP2 and GeoIP Legacy License

I would like to use a GeoIP2 or GeoIP Legacy database on xyz.com, xyz.ca, and xyz.biz. Do I need more than one site license?

只要您拥有、经营这些网站并具有专有访问权,您只需要一个站点许可证。

We are a hosting provider and have a license to one of your GeoIP2 or GeoIP Legacy databases. Can we install it on the different servers that we provide to our hosting clients?

No. While you can install the databases on multiple servers, they can only be used for internal business purposes. Any company that has access to GeoIP2 or GeoIP Legacy data and databases must have their own license.

Can I set up a website where my clients can enter an IP address and get GeoIP2 information back?

You can use a GeoIP2 Web Service to offer this service.

Using the downloaded GeoIP2 database to offer this service is not permitted under the license agreement.

minFraud服务

在减少交易退款方面,MaxMind的效力如何?

MaxMind的minFraud服务能够有效检测到窃卡欺诈。 MaxMind的服务无法防止 “善意”退款,即持卡人下单后又否认曾经下单,并要求退款。

我应如何向MaxMind举报欺诈行为?

您可以使用网络表格或我们的HTTP API来举报欺诈。

通过向我们举报欺诈,您将帮助我们改进服务。

我能否自制调整minFraud服务得出风险分数(riskScore)时所用的算法?

您不能改变MaxMind计算风险分数的方式。 但是,除了风险分数以外,我们的 minfraud服务还会 生成许多其他项目的数据分数 。 您可以基于这一数据,用您自己的代码实施自制规则。

如果您向我们 报告退款行为 ,我们会使用该信息改进风险分数。

如果您对 屏蔽国家名单 作出调整,那么当订单来自您所指定的高危国家时,您所观察到的风险分数会受到影响。

我如何确保minFraud服务能够为我发挥最大功效?

First, if you are still using minFraud version 1.0, we recommend upgrading to the latest version of the minFraud service. Upgrading from version 1.0 gives you access to the riskScore, which represents the likelihood that a given transaction is fraudulent.

Second, we recommend you use the riskScore rather than the score as you make decisions about whether to accept, reject, or review orders. The riskScore is based on sophisticated statistical modelling and real-time data feeds while the score uses a simple formula. As such, the riskScore better indicates whether a given order is fraudulent.

Third, the more input fields you pass to the minFraud service, the more accurate the riskScore will be. In particular, we recommend passing at least the city, postal, country, bin, user_agent, and accept_language fields.

Fourth, we recommend you use the Device Tracking Add-on for the minFraud service on your site. The add-on helps catch fraudsters who change proxies while they are browsing your website or between visits to your website.

Fifth, you can help us improve the riskScore by reporting fraud and chargebacks to us.

我是否可以通过一个账户兼用标准及高级minFraud查询?

如果您订购了两项服务,您可以兼用标准和高级minFraud查询。

您可以使用 requested_type 来指定您是想 使用标准还是高级minFraud服务。

标准和高级minFraud服务有何不同? 我应该使用哪项服务?

大多数客户使用的是标准服务。 高级服务可就信用卡的发卡银行以及该卡是否为预付卡或礼品卡提供更多信息。 如需更多细节,请参阅我们的 minFraud功能对比 页面。

minFraud服务是否可以检查来自所有国家的订单?

是的。 minFraud服务可以检测到来自任何国家的欺诈行为。

我运营多个网站。 我是否可以将同一个minFraud账户用于这些不同的站点?

是的。您可以用同一个minFraud账户检查来自多个站点的订单。 你可以用 shopID 来指明订单来自哪个网站。

什么是minFraud警报? 我应该用它做什么?

minFraud警报是当一个已评分交易的风险可能升高时所发出的通知。 这些警报作为对一个您确定的URI所做的网络查询而发出。 您可以 设定我们查询并示警的URI。 您还会就所有警报收到一封电子邮件。

minFraud服务是否与PCI兼容?

我们已经与Visa公司确认,minFraud服务不需要与PCI兼容,因为它无需获悉全部16位信用卡号码。 但是,我们对数据安全非常重视。

按月订购的未用查询次数是否会转入下一个月继续使用?

是的。未用查询将被结转,不会过期。

贵公司是否会就交易退款向我作出补偿?

不会。 虽然minFraud服务可以用来识别欺诈性交易, 是否接受或 拒绝某笔特定交易的决定权要由客户负责。
